CASH-REGISTER.

17 o all whom it may concern Be it known that l, THOMAS CARROLL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new andnseful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in cash registers. Y

(.)ne of the objects ot' the invention is vto lessen the number ot parts and simplify the malte-up in a construction tor totalizing, indicating and'printing the amounts of transactions set up by a series of controlling elements, thereby relieving` the machine of considerable weight and greatly reducing the cost of manufacture.

Another object is to provide improved devices for actuating the rcgistering'mechanisni by an operating handle or lever and controlling such operation by a. series of pre viously manipulated setting` elements.

A further object is to provide an in'r proved indicating' mechanism whereby suit.4 ably inscribed disks or members may be moved from one indioating position to another .vi'thont haringto be first returnedl lo a Zero or initial position.

lil/"ith these and certain other objects in rien', as will be hereinafter apparent, the invention consists in certain novel constructions, combinations and arrangements of parts, the essential elemei'its of Whichwill be found recited in the appended claims, and a meierred torni or' embodiment as described in detail in the following specifica-- tion and fully illustrated in the accompanyin.lo di'avinzg'sy forming part thereof, and in which:

In order that the general. features et the present invention may be more nllynnderstood, before entering into a detail descrip tion of the diliierent mechanisms, the arrangement and functions of the most imporceA tant operating elements of the machine will i be described.

The amount keys J. are arranged in groups or banks and represent numerals from one 'to nine. Willen a ley oi any one of these. banks is'depressed it engages one ot a series of pivoted levers 3 and forces the saine rearward to an extent equal to the value of the ley operated. (See Fig. 5.) The lever 3 ls pivotally connected to a racle bar et which is carried rearwardly with the lever and. is then forced into mesh. with a segmental. raell: 5 mounted upon. `an oscillating;y segment G.

vhe lever is then returned to its normal position tl reciting the scgniet.; o u extent equa, to the value the la ated.. Said segment G mes es with a cally' sliding rack har 7. This bar is 'orovidedwith 'counteroperating recit teeth 8. After this rack is seon the manner above described, a counter 9 is drawn downward over the same and 'thereby actuated. .il

lposition of lhis lever l is pirotnlly connected to a vertically sliding ruck bnr 1l, arranged to actuele rotary indicator l2. The lever l is provided with :in enti riclion roller l mounted about n'iidwny of its length. After the bnr "i" is set7 :is shove described, the unti- 'lriction roller 'lf3 rammed to n. common position sind the lever lL) thus nctnnted to operate the bar ll to the indicator.

lfereeiter follow." e detail description of the dili'erent parts 'oli' my invention:

fly/'Le ,tw/gfbaarde-Ehe keyboard comprises spnced plates and lo snitsbiy secured nlnni the moin freine l of the machine end epertnred to recei'if'e the square Shanks 17 ol' the keys. Coil springs i8 surround the shrinks intermediate the two plates 1 5 and 'i6 and engage said lett-er piste and pins i9 projecting "lroni the Shanks whereby the keys, when depressedj will have a tendency to rcsln'ne their normal positions.

Each of the keys is, oif course', Jprovided with :i character, nnnrerel, or @hier designation upon its end.. Each of the .key Shanks is formed with :L notch 2G whereby when the key is depressed, it will be locked in this depressed position by n siidine syertured detent plate 2l, mounted under @he piste l@ land normally' drawn dowinrard by e. coil spring which connects en erin ol seid plaie to the 1min renie7 best shown in ifi The erin pro fidcd with :i pin an elongated notch 2l which projects into forme/il in en l'- on e. rocksheit 2T. fs/'her ihis shaft 2?' rocked3 the detent plate 'fl forced in v eff i ing and s E are reiceed :3nd n ormai p ositions.

Main opermng elemente-.Lach of the ei'oresuid levers 53 is journfiled upon e transverse shaft 28 and is normally forced forward nguinst e. stop fnnge 9,9 by s coil spring 30 which surrounds said shaft 28 rind beers with its opposite ends, one against :itie bar 3i of the main ironie and the other lgsinst said lever. (See Fig. 5.) 'By reference to said figure it will be seen that the iforwsird edge of the levers 3 is curved or graduated in relation to the ends of the key Shanks 17', whereby, when the dil'i'erent keys are depressed, their Shanks Will engage said lever sooner or later during their movements and thus move the lever dierent olistences according-"to the velue of the keys operated; vThe rack bar 4f is pivotelly connected at its forward end to its respective lever 3 and is for-ined near .it rear end with en elongated slot 33 through which passes a 'trensverse shaft 34:. es peinly shown in Fie. 5.' reference to this gure it Will be seen tnzn the rackteeth upon the bar el are normally clear of the teeth of the rack 5 so that the ber may be moved freely back with the ies/'er Si without engsgingthe rack 5. When she shaft 341.; is-siightly degressed, however, ehe reet-h ofthe reckbzir e ere brought into mesh with the segmen 5 so that any subseqi, nt inni/*ornent of the ber Wili be imparted 'to the segment G.

'ie eecempiss the shore result the shaft 3e is supported. heb/veen forward ends of two pveted levers 36, best shown in Fig. o. fhese ieyers are piv'oteliy mounted upon the rhein frame and are provided With enti friction rollers 37' which project into the @ein grooves 38 of box earns 39, fest to 'the rotation shaft il. this construction., .rhen'the shsf el@ is rotated the levers 3G are rocks eno reeks thus brought inte n'iesh Wirth 'she Aients 5 during a m eertein period and then disengaged from the seme, The segments 6 are jonrnsied upon :i transverse shaft and are formed with two series of rack teeth lo end e?. rEhe teeth 4o mesh r-ith rack teeth d8 formed on. Verticnlly siding; bars 'i' which are suitably n'ionnted in the main These bars i are also formed with toteizer operating" ruck teeth 8 which will be hereinnliter more fully described.

fitter A'the lever 3 has been forced rearward and the rack teeth moved down into mesh with the rack 5, seid lever is returned to itsnormnl position thereby rocking the segment end elevating' he bar 7 e disance pronertionne to' ther/turn movement of seid lever. This return of the leverr is el'eeed by n transverse rod 49' mounted in the Lipper ends of 'We arms 5G which ere t? ms cater Will not be returned toits normal posin tion, but will be moved directly from the l' position to the .9 position.

)ft Will be seen from the above that either one or the other of the operating cams for the indicator levers will engage the projections upon said levers and operate the lever according to its previous position. 1When one of the cams is movingthe lever the other Cain performs the office of an overthrow device and prevents the lever, when it reaches its neutral position, iroin moving past the saine.

From the. above description it will be. seen that the rack bars 7 and .il are mehr. bers of a couple Which are always connected lby the lover 10, the member '7 of said couple being first positioned upon the operation of the machine and by its position control.- ling;` the extent ci movement imparted to the other member ll oli the couple.

lt will be seen by reference to Figsl 1 and. 2 that the amount indicators l2 arc arraiiged in two groups tor indicatingto both the back and front of the machine. As the rac-lr bars ll are arranged to actnate only one of its groups of indicators it becomes .necessary to provide means for colliding the respective indicators of the tivo groups so that they will move together. This acconsplished in the following manner: The unitsoi-cents indicator is provided with a Igear' Wheel 87, best shown in iigs. l and 2. 'This ,einer meshes with a, pinion 8S, t upon a trans *ers/e shaft Si), which sha'if. s provifed at .its on iosite end with a similar iinion L i 9i, tast This pinion 90 meshes with to the companion unitsoi`cents indicator arranged at the opposite end of the niachine. The tensoicents indicator i2 is provided with a gear wheel. 92 which meshes wiwi a pinion 933 ifast to a trsinsverse shaft 9d. This shaft .is provided near its opposite end with a pinion which meshes with a fear Wheel QG tast to the tcns-of-cents in-l dicator l2 near the opposite end of the inachine. 'l`he 'units-oii-dollars ii fflicator l2 is provided with :l "rear wheel Si' rich meshes with a pinion d rast to a sleeve 99, which is jom'ualed upon the sl .itt let and i" provided at its opposite end with a similar pinion l0() meshing with a gear lOl. inst to the coin.- panini nnits-ofdoliars iinlicator. lBoth oit the tempt-dollars indicators and l2 are mounted fast upon the imlicatrs' shaft i3 soV as to be sininltaneimsly :.idjustable. lihe two cleiilrss indicators if] and are mounted upon the opposite ends ci. a slew-:e '102 which joi'unaled upon the aioi aid shaft ri`he special indicator l2@ vfor indicating the special trai'isactions. such as i charge, ceived-on-account, 3' aid out. and casa, is jonrnaled upon the shaft di?, and is provided with tvvo series of ehai'act vrs or wor which are so arranged thereon as to indi! 1 noot/ros cate properly to both thedback and front of the machine. For this purpose the special indicator may be said to be divided into two sections, one ot' Which is about twice the width of the other, whereby a much larger and more prominent indication may be made" to the front of the machine, as shown iny Fig. l. This construction is practicable be, cause this large extended portion of the indicator projects over the back of the indicators indicating at the oppositeiside .of the machine and out of the path of any of the operating parts.

It will be seen troni thc foregoing descripticn that the indicating mechanism is arranged to indicate the character of the transaction, a designating mark for the clerk making;- the transaction, and the amount of the transaction, at both front and back of the machine.

The guard or flash clcocea-ln order to prevent any readingn of the indicators during; the time the saine :re being moved or adjusted, l provide two flash plates 44 .arranged to conceal the indicators at the opposite sides of the machine. The levers 36 are connected at their rear ends to link bars l-l which are in turn connected to pivoted levers #i2 journaled upon the indicator shaft and connected at their outer ends by the jiiash plates i-ft rotors at both the back and front of the machine. cinst as 4soon as'the racks 4 are brought into mesh with the segments. 5 the flash plates 4eiare moved into position to obscure the indicators and are not Withdrawn from these positions until the racks and segments are again disengaged.

T71 e total/[sing or vref/stering mechanism. As before stated, each of the'bars 7', excepti i of course the bars relating to the clerks bank and the special keys bank, is provided with a 'rack bar 8, "When the bar 7 is ad-v jnsted according to the value of the key operatcd` as before described, a greater or less number oi the teeth ot the rack S are broughtinto a. plane that is `normally traversed b v the totalizer 9 when the saine isv moved downward in the manner above de` scribed. The positions oi? the bars? are such that the rack piates or extensions formed 'with the teeth S innst be oliset or moved into closer relation with each other in order to bring` thcni. into 'the proper positions t0 cooperate withthe tot-alizer pinions. The registeringY mechanism shown inthe present ease is fully illustratedand described in my llalent hlo. 7515611 dated Feb. 9, 1904,. and is peculiar in that the totalizer comprising` the registering Wheels 103 is mounted in a movable frame which is 2Fgiven a deiinite and constant movement or excursion every time the crank isoperated. The operating rack bars are iidjusted, as before described, to the proper registering positions iso arranged to obscure the indiin a manner well known in the art. The pawl 128 cooperates with its tripping pawl substantially in the sanie manner as above described except that it is provided with an arm 130 which engages its tripping .pava/l as plainly shown in Fig. 12.

The totalizer frane carrying the totalizer wheels is slidably mounted in e rock traine 131 which is pivoted upon the main traine and is formed With vertical guiding grooves 132 into which project anti-friction rollers 133 which are mounted upon the sides ci' the counter traine. Lateral movement of the totalizer frame is prevented by flanges 13% which lap over the edges of the slots 132 whereby the totalizer trarne is permitted only n vertical movement. The totalizer is given a constant and definite vertical travel within the rock frame upon each operation of the crank handle. This result is effected by means of a totalizcr reciprocating lever 135 which is pivoted at its rear end to the main frame and is slotted at its 'forward end to straddle a rod 136 which connects the lower ends oi. the counter traine plates. The lever 135 is provided with an miti-friction roller 137 which projects into a cam groove 138 formed in a box cain 139 which is mounted upon the rotation shaft 10. 1tresults from the above that upon each rotation of the shaft 4Q. the totalizer frame is moved first downward and then back to its norinal upper position. 1n addition to the above the 'frame 131 is tiret rocked rearward and then subsequent-l.7 forward to its normal pon sition. This rocking oit the 'trame 131 is accomplished by means of a link bar 1110 which is slotted at its rear end to straddlc the shaft L10, und is provided with an anti-frio tion. roller 111-1 which projects into a cam groove H9 formed in loo); cani 113, fast to said shaft 10. The formation of this box cam such that the link bar is given one rcciprocation upon each operation of the machine. rthe forward end of the link bar is formed with an .elongated slot 14% into which projects a pin 115 projecting laterally from the rocking traine 131. The pin is normally latched tornove with tho'loar 1410 by a pivoted latch 1416 which is mounted on, said bar and is formed with a hoolt 147 which engages the pin 1-15. shown in Fig tu. 'The hook i7 is normally held in engagement with the pin 145 so that the trame 131 will. move with the har 140 by one arin 118 of a lever 149 which is mounted upon ay transverse shaft 150. The arm 11S engages a pin .151 which. is mounted upon the pawl 146 .to normally hold. the latter in poeition. The lever 1/19 is formed with an upper hook arm 152 Whiclnwhen the shaft is rocked, is arranged te pase down over the pin 111-5 ond thus lock the frame 131 in its forward position. lhl shaft 150 is 'rocked to secure this result l l l l l i l neer/,voe

the following;` manner: Fast to one end of said shaft is an. operating arin 153 formed with an angular slot 154: into which a pin 155 projects. This pin is mounted upon the upper end ot an arm 15G which is fast to the segment G of the bank of keys relating to the special transactions. 1vl'lhenever the segment t3 ol thisl .special bank rocked forward fo.li m'ing` the moeration of one ol the special keys, the arin 15G also rocks .torward and the pin 153 engaging the cam walls oit the slot 1.1i torres theht'orward end of the arin upward and thus rocks the Shaft 15G to engage the hook 152 with the pin 115 and disengage the pawl 11G from the piu 145. The euhsequent operation of the crank hundle will then result in the tree movement ofthe link har irl-0 without att'ectiug the rock trame 131. .1s theroek frame is not moved to its` rear position the totalizer pinioue ol course do not engage the rack teeth S and no regi tration takes place. rl`he totalizer shatt 105 is provided at one end outside ot the ruck iframe 131 with a locking disk 15T :t'ormcd with a flat Side 158 which, when the totalizer is moved down-- ward7 passes in 'front o t a flange 1:19 tornied on the rock frame and thusI prevents any turning ot the totalizer .shaft 105 after the totaliz/.cr frame has been moved from its nor-y mal position. The shaft 105 is provided near its end with a notched collar 1(30 where by a key may he applied thereto 'to rotate it and thus turn the counter wheels to Zero. Suitable spring' pressed pawls 160 are mounted on the counter wheels and are ai ranged to engage a lono'itudinal groove formed in the shaft. 105 whereby, when the latter operatedj thc counter wheels are picked up and returned to u common zero position. The disk 157 is provided with :i pin 161 which7 when the counter shaft is rotated, contacts with ay stop pawl 162 (see 6) otter the shaft made a complete rotation and thus arrests the totalizer Wheels in their zero posit-ions. rthe pawl 162 is pivotally mounted upon the rock traine 131 and is normally forced rearward into the position shown in (5 by a spring ,163 which is wound about it' pivot pin loft and bears with one endagainst tlieitrame 1tl and the other against a projection 165 of the pewl. pawl. 162 ie'tornied with a. stop arm 165 which. when the pawl is forced'iforward, contacts with the edgeI of the traine 131 and thus limits` the ,movement of the pawl in this direction. ltttler lthe totzilizer has been turned to zero, ,as above described, the pin 161 will lie to the right'ot the pnwl 162. W hen the totalizcr is Ysuhsequently moved downward the pin will` disengage from' the paw] Aand the .attefwill thus asnorrunl position s that when the n the pin 161 on the lett `tootl1ed elimini;

of tlie paw] leaving the totelizer shaft 'tree to lie rotated to turn the totelizer Wheels to zero when desired.

lt will 4be seen from the' above descrip tion thu-t the reak bers 7 are first set., tlie rookv freine' 31 then roe-lied reeruf'erd to bring the totslizer pinions into the seme vertical pleines with the ruoli teeth 8, the totaiizer tlien moved downward over the ruoli teetli and tuereby operated, the .treme 131 then rocked forward and the totalizer thereby returned to its upper normal position; the transfer taking place es the to'telizer moves upward. The Construction of the operating link rods und box cams is suoli that when tlie totelizer rea-ches tf'ne lower limit of its trai-'el itis not immediately moved out ot Connection with the reel; oars but n sufficient interval ei rest occurs to insure the a solute termination of the rotary movement tlie totalize'r Wheels before they are moved out ot mesh with the miek bers.

Printing meehfmv'smf-s before stated, eueli of the segments@ is formed with e series of printer operating rack teeth 47. These vteeth uiesli with pinions 167 that ere mount ed :upon the inner ends of e series of nested sleeves 168 and e she-ft 169 which supports seid sleeves. Mounted 'upon the opposite ends of the sleeves and the shaft are tlie type Wheels 14. iliesewheels are formed with double series ot1 types loeeted upon diametrioally opposite sides oi? the sume whereby un impression of the amount and other eherueters maybe token botti trom the top and bottoni of seid Wheels. The upper printing; line is utilized 'for printing upon the det-uil strip while the lower printing line is e. rnellium 'tor the print-ing oie. the Cheek. lil-ach of the type Wheels is provided with u disk lSSa fast thereto. These disks ere arranged to be engaged by e series of dining @owls 169. 'tliese pewls are formed upon s plete 170 which is pivoted upon u transverse sliett 171. Two arms 172' sind 173 project from the plete 176 uud :ire actuated by joins 174 end 17 tast to the printing roller 176, which is jouruuled upon the' printer frame. The roller 176 (ferries u. oem disk 177 which is orrunged to engage u pin 178 projecting from. the erm 1731 During the proper period or the rotation of the cylinder 176 the pin 178 is engaged by the eem/disk 177 und thereby forced downward to cause tl'ie parels 16) to engage und lock the type wheels. litter the i: pression has been mudo from the wlnels the suine are unlocked, as shown in Fig'. 3. bj tlirenlarged portion ol the aero disk 177 pussingr tree of the pin tiu's -17 l und 175 t-ruverse the arm 172 and thus -old tlie puwls 1139 out of engagement with the toothed disks .168 'until the proper time is reached for again looking tlie typo wheels. The devi/.ees for feeding tlie detail und olie'elr strips end for cutting ott" the letter are con troll-eel from the rot-ation slieft 4 0. For this purpose the shaft is provided with e gear 179 which meshes with o pinion 180 meurt-.t`- ed 'fest upon. the elio-rt rotation shaft 181 which is journsled ut one end in the mainframe and et the opposite end in e sleeve 182 which is in 'turn journeled in the printer iframe. (See Fig. el.) This sleeve is pro* vided with u pinion 183 which meshes with e gear 18st mounted on 'the end of the print ing cylinder 176. The gear A184i meshes with. u. similar geur 185 mounted upon the end of the impression end feeding roller 186 which is journeled on the mein freine. The shaft 181 is norniully coupled to tlie sleeve 182 by piu 187 which projects laterally" from the slisit int-o u notoli 188 formed in 191. The bolt 189 is provided with e laterelijy" projecting pin 192 extending into e diagonal slot 193 `formed in e spring pressed operating); plate 1911. This plete is mounted on the sleeve 182 und normally-'forced toward the outer end of tlie sleeve lijf e. coil spring 195 Wl'iioli engages the disk 19S uiounted'on the rod 197 extending from the plate und the shoulder 198 formed. on the sleeve. knob 199 is mounted test ori the outer end ot the sleeve 18:2 and is formed 'ith n centre] aperture through which projects u. plunger stud 200 mounted on the plete 1%. '.By reference to it Will be seen tliut the teeth o' tlie pinion 183 ure unobstructed `tor lateral outu'urd movement when the parte ure in their normal positions. as shown. linnen tlie parte are moved from suoli norinul positions by rotation, however. the enlarged port-ion of the oem 177 will over-iup the teetli of the pinion and thus pre nt any lateral movementot' the seme. lllher it is desired -to uneoun ple, the sleeve 182 om the Sluitt 181 the stud 200 is forced inward thus drawing the bolt 18) downward und disengeging it from the oep 190. llie knob 199 is now drawn outwardv to disenguge the sleevetrom the piu 187. Upon 'the plunger 200 being released the ooit 189 posses up outside et the cup 1550 und thus prevents the return of the sleeve 189. to its coupled positie/rz. lt will be obserted that tlie eetior. ot 'the spring 195 eutomutitully returns the boltilt. lto its norms] position when pressure upon the stud 200' is removed. When the sleeve 182 is drawn outward in the manner abovedescribed, the operation of the printiing cylinder ceases? sind as this cylinder also fontrols the movement of the roller 186. all feeding the cheek stripelse stops.

' 201. The first oscillatory movements et the addition to the above the lower platen is also rendered inoperative by this adjustment. This platen is mounted upon a lever 202 and is provided with an anti-friction roller 203 which projects into a cam groove 204 formed in a box cani 205 which is carried by the roller 186. The cheek strip is led from a supplyv roller 206 down through a. chute 207 and forward between the printer roller 176 and the pressure roller 186. lThe check strip passes forward over the platen 201, through an opening in a stationary knifeblade .208, and over a pivoted knife blade 209. This latter blade, as best shown in Fig. 1, is formed at its inner end with an elongated slot 210 into which projects a pin 211. This pin, as best shown in Fig. 10, is mounted in a short link 212 pivoted to the front of the lever The rear end of this lever is provided with an anti-friction roller 21-1 Which projects into a cam slot 215 formed in aboli cam 216 fast tothe shaft 40. By this means the movable knife blade is oscillated once upon each operation of the machine and severs the check strip which has been fed between it and the stationary blade.

Any suitable form. of ink roller, such as 2l?, may be provided for inking the types on the cylinder 176. This cylinder j'n'et'eraloly contains dating` and consecutive nun'ibering types. The platenroller 218 for the detail strip is mounted uponthe forward end ot the lever 219 which is pivoted upon the printer frame, and receives motion from a lever 220 also pivoted upon the printer trame, and connected to the lirst mentioned lever by scr'ew bolts 221 .vherehy the relative positions of the two levers may be adjusted. The rezar endI of the lever 220 is provided' with an anti-friction roller 222 which projects into a cam slot 223 formed in a boxvcam 224, which 'is to the sl1at`t'40ilt results-trom the above that the lever 219 is oscillated twice upon each operation olf the machine in a similar manner to the platen platens is :for p essing the ink pads 225 against the types on the printing lines. rlhese ink pads are carried by pivoted spring pressed arms 226 mounted upon levers One o't these levers is made i'ast to one end of a short sleeve 1689"(see Figs. 1 and 16,) the other end of which carries a pinion 163D;

this pinion. is ope 1ated by a rack bar which is slotted at its rear end to straddle the sha ft Il0 and is actuated by a box cam 229 mounted thereon. rflic formation of the com 229 is such that the ink pads are 'first brought to the printingline and then subsequently moved away from the ine so that the tivo platens may force the'detail strip and tlte check strip against the ink types. The detail strip passes from supply roller 230 mounted on the main frame, aboutr the platen roller 218, and to a winding roller 231, which is mounted upon said lever 219. This winding,` roller 231 is provided With a milled disk which is last thereto and .is engaged by a spring pressed feeding'pawl 233. This paivl is mounted upon an arm 234. which is journaled upon the lever 219 and is connected to the mainv trame by a link bar 35. lt results troni the above construction .that when the lever 21S) is operated the arm 234 is drawn Aupward and then as the lever 21S) returned to its normal position the arm 28st is forced downward whereby the pand 233 rotates the disk 232 and v. inds the detail strip upon the roller 231. A spring pressed reta ining` paivl is mounted upon the lever 219 and engages the disk 232 to prevent any retrograde n'ioveluent oi the saine. j

It will be observed troni the above description that the detail printing` devices are continually operative While the check printing devices may vbe discontinued at will by simply disconnecting the sha 'lt 182 'lroin the shaft 181.

As many ot' the" parts ol the present printer are covered by the patent above mentioned, they .have not been described in minute detail a general description otl the parte only having been given.

lll'az'n, operai/inf; gearingf-'lhe crank handle 23.7 is j ournaled upon a. stud 238 mounted on the main trame and is jn'ovided with a pinion 23S) which meshes with a gear 240 also journaled upon the main Ytrame and n'iesliing` in turn with the ejear Stil which is 'tast to the shaitt 40. ils betere stated, the giar 3G meshes with a `gear 40" and this gear carries a locking disk 2-11 Formed with a.- locking notch 242 and provided with a trip pin 243. .ik spring dra wn locking` paivl 22H is suitaldy mounted upon the main trame and is provided with a beveled nose 2115 arranged to project into the locking' notch 242. The pawl 2-1-1 is formed with a stop arm 2li-(3 and a trip arm 24T. llvlhen the parts are in their normal positions shown. in Fig. 7. the machine is lof-kerl and in order to unlock it, it is neces-:ary to first force the handle 23 slightly to the rear. This operation dise gages the panl 2441 from the inclined Wall of the notch 24-2 and permits the paWl to' be drawn by a coil spring' 24:8 into a position in which it will not be engaged by the wall of the notch 243 when the handle is again moved orward: The machine is then operated. As' the disk 241approaches the end of its movement the pin 24.3 engages the arm 247 and again forces thepaivl 244 into engagement to arrest the movement ot the machine.

The locking iev/fees for t/m operating mec/Lansm.--ln machines of the type herein shown it is very desirable to lock the mechanism aeainst anT o aeration until after some clerks keys, the arm is forced one of the clerks keys has been operated. To acco-mplish this result is provided the key-board with a pivoted lever 249 located 'immediately' below the inner ends of the key Shanks of the special clerks7 keys. lt results from' this construction that whenany one of the clerks keys is forced inward it contacts with and operaties the lever 249% This movement of the lever is utilized to unlock the machine through the medium of a link bar 2503' which is pivotally connected at its forward end to said lever, and at its rear end issimilarly connected to a bell crank lever 251 which is pivoted upon the shaft 66 and is normally rocked forward into the position shown in Fig. 8, by a spring 252 which surrounds the shaft and bears with its opposite ends -one against said bell crank lever, and the other against a portion. of the main frame. The upper or elongated arm of the bell crank lever normally projects into a. position to intercept loclc ing projection Qif fast to the shaft d0. lhen the bell crank lever op ted5 however, by the depression of one oi" the so to the rear as to pass free ofthe stop Qca and thus leave the shaft t0 free to rotate. 'When the clerks key is released in the manner heretofore described, the parts assume their normal locking positions and the machiiie is arrested after the crank handle has made two complete revolutions. y

Gef/icm? description-From the foregoing it will be observed that the depression of the ykeys set certain parts to degree corresponding to the values of the keys operated and that these setting movements are subsequently utilized to secure the desired reg'fis tration by returning the set parts to normal fixed positions. It will be further seen that Aeach of these second graduated movements accomplished by the return of the originally set device to its normal position is utilized to determine the position of the fulcrum -of a lever; which lever is connected to the indicating devices. After the fulcrurn of this lever has been determined,l a projection mounted on the lever ismoved to a certain fixed 'point and the lever thus given a move ment 'dependent upon the adjusted position of its fulcrum. ln practice the indicators .and their operating racks are all constructed sufficiently tight in their bearings to require a positive force to operate them. For instance; should a certain indicator wheel be set to indicate 9, the initial movement of the operating handleupon thenext succeeding operation of the machine will release the indicator by the camslS and 86 passing free of the. roller 13 but the indicator will not ordinarily move' away from the 9 position ,until it is actually forced to do so by the lever 10. Should the indicator be at 9 and another transaction includcounter as the setting movement of, the in- 5o dieators and. the momentum' of the same have no effect upon the setting movement of the counter operating elements. ln fact the Acounter operating elements are set and locked before the operation of the operating devices has conurenced.

it will be observed that keys of the machine shown are adapted to cifierentially position movable elements whie ,einselves serve to differentially actuate adding eounet ter or 'totalizer controlling rackst The movable elements and totalizer controlling racks therefore form primary and secondary positicninef devices. it ,will be clear that although there are shown in this case banks e5,

of keys which serve to vpositively move the primary positioning devices ditlerentially the invention is notlimited to the use of this type of keys, as any other known devices in the art for producing directly or in-V let directly? a differential positioning of said devices are comprised in" the inventionJ broadiy stated. It is therefore desired that 'the claims should no t be limited -to the type of keys and positioning elements shown, but

may include other means, as pointed out! above, and may be construed broadly except as limited by the prior art.. lt will be seen that the construction herein described and shown, is well calculated to thoroughly fulfil lthe objects primarily stated. At the same time is to be under stood that the invention 1ere described is susceptible of embodiment in many other forms which will be more or less obvious to those skilled in the art; hence in the claims which follow essential elements are recited without limitations to details of construction.

The invention whichrelates to the char- 12C acter Iof means for positioning identifying devices in a cash register or analogous machine in such manner as to obviate restoration tofzcro ineach operation, does not at all depend upon the exact :function which the identifying devices perform; and while these identifying devices are termed 1ndicators m the claims, this is not to be taken in a limited sense as meaning spe'cilically display devices or targets for 1t will be 130 registered, the indicator will only 70 This construction results in a 75 indicator Vsa :form of dm mr W.
